My laptop looks like overheating

I bought a new laptop, and when I was about to add an SSD of MICRON: :http://www.kynix.com/Detail/579339/MTFDDAK480MAV.html, I saw this. The store tells me it's nothing, and if anything, just flux residue from production.

To me, it looks like overheating. That is; a bad connection or something is causing a lot of heat, and thus these brown and dark spots around, especially the leftmost pin, and a black area on the edge of the PCB.

What do you think? Doesn't it look like it is burnt?









Let me add an extreme close up for details: http://amews.net/ExtremeCloseUp.png

What about the edge - seems like it has been damaged (not a sharp edge anymore) - does that matter?

What about the brown color on the connector itself ? I suppose that the connector would not be plugged in while soldering. How should flux end up there then?

I would agree with the overheating and not the flux residue theory. Notice any smells that weren't there previously? (As if you sniff your laptop daily :-D)
